Chapter 1 An Overview of the Cisco Unified IP Phone
Understanding Security Features for Cisco Unified IP Phones
Best Practices—Requirements and Recommendations
• Enable 802.1X Authentication—If you want to use the 802.1X standard to
authenticate Cisco Unified IP Phones, be sure that you have properly
configured the other components before enabling it on the phone. See the
“802.1X Authentication and Status” section on page 4-50 for more
information.
• Configure PC Port—The 802.1X standard does not take into account the use
of VLANs and thus recommends that only a single device should be
authenticated to a specific switch port. However, some switches (including
Cisco Catalyst switches) support multi-domain authentication. The switch
configuration determines whether you can connect a PC to the phone’s PC
port.
– Enabled—If you are using a switch that supports multi-domain
authentication, you can enable the PC port and connect a PC to it. In this
case, Cisco Unified IP Phones support proxy EAPOL-Logoff to monitor
the authentication exchanges between the switch and the attached PC.
For more information about IEEE 802.1X support on the Cisco Catalyst
switches, refer to the Cisco Catalyst switch configuration guides at:
http://www.cisco.com/en/US/products/hw/switches/ps708/tsd_products
_support_series_home.html
– Disabled—If the switch does not support multiple 802.1X-compliant
devices on the same port, you should disable the PC Port when 802.1X
authentication is enabled. See the
“Security Configuration Menu” section
on page 4-37 for more information. If you do not disable this port and
subsequently attempt to attach a PC to it, the switch will deny network
access to both the phone and the PC.
• Configure Voice VLAN—Because the 802.1X standard does not account for
VLANs, you should configure this setting based on the switch support.
– Enabled—If you are using a switch that supports multi-domain
authentication, you can continue to use the voice VLAN.
– Disabled—If the switch does not support multi-domain authentication,
disable the Voice VLAN and consider assigning the port to the native
VLAN. See the
“Security Configuration Menu” section on page 4-37 for
more information.
